Example Embodiment
[0074] Example 2
[0075] As shown in Figure 2, this example is two parallel clarification zones. Under the condition of a glass flow rate of 10 tons / day, the clarification zone is designed into a cylindrical shape. According to certain experience and theory, the diameter, wall thickness, and length of the clarification zone are determined as shown in the corresponding row in Example 2 of Table 1. Compared with Comparative Example 1, the amount of precious metals in Example 2 is 20.48 kg less; the glass temperature difference is reduced from ±3°C to ±1°C; the number of bubbles larger than 0.1mm per kg of glass plate does not exceed 0.5; The operating temperature can be reduced from 1680°C to 1650°C; the life of the clarification zone is extended from 21 months to 26 months.
Example Embodiment
[0076] Example 3
[0077] As shown in Figure 3, this example is three parallel clarification zones. Under the condition of a glass flow rate of 10 tons / day, the clarification zone is designed into a cylindrical shape. According to certain experience and theory, the diameter, wall thickness, and length of the clarification zone are determined as shown in the corresponding row in Example 3 of Table 1. Compared with Comparative Example 1, the amount of precious metals used in Example 3 is 36.65 kg less; the glass temperature difference is reduced from ±3°C to ±0.7°C; the number of bubbles larger than 0.1mm per kg of glass plate does not exceed 0.2; the clarification zone The operating temperature dropped from 1680°C to 1620°C, and the life of the clarification channel was extended from 21 months to 26.5 months.
[0078] Through the above examples, it can be clearly seen that when the glass flow rate is 10 tons / day, the two examples using parallel clarification zones are more effectiv...
Example Embodiment
[0081] Example 5
[0082] As shown in Figure 2, this example is two parallel clarification zones. Under the condition of a glass flow rate of 12 tons / day, the clarification zone is designed into a cylindrical shape. According to certain experience and theory, the diameter, wall thickness, and length of the clarification zone are determined as shown in the corresponding row of Example 5 in Table 1. Compared with Comparative Example 4, the amount of precious metals in Example 5 is 35.68 kg less; the glass temperature difference decreases from ±3.3°C to ±1.5°C; the number of bubbles larger than 0.1mm per kg of glass plate does not exceed 0.6; The operating temperature can be reduced from 1680°C to 1650°C; the life of the clarification zone is extended from 19 months to 24.5 months.
